Substitute Part Grouping Explanation

Substitute parts for the RS07D-M-18 are classified into two functional categories based on electrical parameter compatibility:

Category 1: Parametric Equivalents (Identical Electrical and Mechanical Specifications)

Parametric equivalents maintain all critical electrical parameters: 200 V reverse voltage rating, 500 mA average rectified current, 1.15 V forward voltage at 700 mA, 150 ns reverse recovery time, and identical DO-219AB package configuration. These parts are direct functional replacements with no circuit redesign required. Substitution is determined by matching:

Voltage - DC Reverse (Vr) Maximum: 200 V
Current - Average Rectified (Io): 500 mA
Reverse Recovery Time (trr): 150 ns
Package / Case: DO-219AB (SMF)
Mounting Type: Surface Mount

Category 2: Manufacturer Recommended Alternatives (Modified Electrical Specifications)

Manufacturer recommended alternatives operate at the same 200 V reverse voltage rating but differ in current rating, package type, or recovery characteristics. These parts require circuit evaluation to confirm suitability for the intended application. Substitution is determined by matching:

Voltage - DC Reverse (Vr) Maximum: 200 V
Automotive Grade and AEC qualification status
Surface Mount technology

Engineering Selection Recommendations

Parametric Equivalent Selection (Direct Replacement)

RS07D-GS08, RS07D-HM3-08, and RS07D-M-08 are parametric equivalents of RS07D-M-18. All four parts share identical electrical specifications (200 V, 500 mA, 150 ns recovery time) and the same DO-219AB package. All are Active product status with AEC-Q101 automotive qualification and ROHS3 compliance. Selection among these equivalents is based on inventory availability and supply chain considerations. RS07D-M-08 offers the highest inventory level at 44,400 pieces.

Manufacturer Recommended Alternatives (Application-Dependent Selection)

BAS21H,115 (Nexperia) is rated for 200 mA average rectified current, representing a 60% reduction from the RS07D-M-18 specification. This part is suitable only for applications where the circuit current requirement does not exceed 200 mA. The SOD-123F package differs from the DO-219AB, requiring PCB layout modification. BAS21H,115 carries AEC-Q100 qualification (automotive-grade) and is Active product status.

CRH01(TE85L,Q,M) and CRH01(TE85R,Q,M) (Toshiba) are rated for 1 A average rectified current, representing a 2× increase from the RS07D-M-18 specification. These parts feature faster recovery time (35 ns versus 150 ns) and lower forward voltage (0.98 V versus 1.15 V). The SOD-123F package differs from the DO-219AB. Both variants are Active product status. Selection between TE85L and TE85R variants is determined by tape reel orientation requirements.

UFM13PL-TP (Micro Commercial Co) is rated for 1 A average rectified current with 35 ns recovery time and 1.0 V forward voltage. The SOD-123F package differs from the DO-219AB. This part is Active product status with ROHS3 compliance.

SM4003PL-TP (Micro Commercial Co) is rated for 1 A average rectified current but carries "Not For New Designs" product status. This designation indicates the manufacturer does not recommend this part for new circuit designs. Standard recovery time exceeds 500 ns, differing from the fast recovery characteristic of RS07D-M-18. The SOD-123F package differs from the DO-219AB.

Frequently Asked Questions (FAQ)

Q: Can RS07D-GS08, RS07D-HM3-08, and RS07D-M-08 be used interchangeably with RS07D-M-18?

A: Yes. These three parts are parametric equivalents with identical electrical specifications (200 V reverse voltage, 500 mA current rating, 150 ns recovery time) and the same DO-219AB surface mount package. No circuit modification is required. Selection is based on inventory availability and supplier preference.

Q: What is the primary difference between RS07D-M-18 and BAS21H,115?

A: The primary difference is current rating. RS07D-M-18 is rated for 500 mA average rectified current, while BAS21H,115 is rated for 200 mA. BAS21H,115 is suitable only for applications where circuit current does not exceed 200 mA. Additionally, BAS21H,115 uses the SOD-123F package instead of DO-219AB, requiring PCB layout changes.

Q: Can CRH01(TE85L,Q,M) or CRH01(TE85R,Q,M) replace RS07D-M-18 in all applications?

A: CRH01 variants are rated for 1 A average rectified current, which exceeds the RS07D-M-18 specification of 500 mA. These parts feature faster recovery time (35 ns versus 150 ns) and lower forward voltage (0.98 V versus 1.15 V). Substitution is application-dependent and requires circuit evaluation. The SOD-123F package differs from DO-219AB, necessitating PCB layout modification.

Q: What does "Not For New Designs" mean for SM4003PL-TP?

A: "Not For New Designs" indicates the manufacturer (Micro Commercial Co) does not recommend this part for new circuit development. While SM4003PL-TP remains available in inventory, it is intended for legacy system support and repair applications only. For new designs, select from Active product status alternatives such as UFM13PL-TP or CRH01 variants.

Q: How do package differences affect substitution?

A: RS07D-M-18 uses the DO-219AB (SMF) package, while BAS21H,115, CRH01 variants, SM4003PL-TP, and UFM13PL-TP use the SOD-123F package. These packages have different physical dimensions and PCB footprints. Substitution with a different package requires PCB layout redesign and verification that the new footprint fits within available board space.

Q: What is the difference between CRH01(TE85L,Q,M) and CRH01(TE85R,Q,M)?

A: Both variants are electrically identical with 200 V rating, 1 A current, 35 ns recovery time, and 0.98 V forward voltage. The difference is tape reel orientation: TE85L and TE85R designate left and right reel configurations respectively. Selection is based on pick-and-place equipment compatibility and supplier tape reel specifications.

Q: Are all substitute parts automotive-qualified?

A: RS07D-M-18 and its parametric equivalents (RS07D-GS08, RS07D-HM3-08, RS07D-M-08) carry AEC-Q101 automotive qualification. BAS21H,115 carries AEC-Q100 automotive qualification. CRH01 variants, SM4003PL-TP, and UFM13PL-TP do not specify AEC qualification in the provided data. For automotive applications requiring AEC qualification, selection is limited to Vishay RS07D variants and Nexperia BAS21H,115.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) determines how quickly the diode transitions from conducting to blocking state. RS07D-M-18 has 150 ns recovery time (fast recovery classification). CRH01 variants and UFM13PL-TP have 35 ns recovery time (faster). SM4003PL-TP has unspecified recovery time but is classified as standard recovery (>500 ns). Faster recovery reduces switching losses in high-frequency applications. Substitution with significantly different recovery times requires circuit performance evaluation.
