Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 23.7 kOhms
• Package / Case: 0402 (1005 Metric)
• Composition: Thin Film
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Compatible Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Temperature Coefficient: ±25ppm/°C or tighter (±10ppm/°C)
• Power Rating: 0.063W or higher
• Operating Temperature Range: Must encompass -55°C ~ 155°C minimum
• Features: Anti-Sulfur and/or AEC-Q200 certification acceptable

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Specifications): Parts matching all electrical and mechanical parameters of the main part, differing only in packaging format (Tape & Reel vs. bulk) or manufacturer.

Upgrade Substitutes (Enhanced Specifications): Parts with improved tolerance (±0.05%), lower temperature coefficient (±10ppm/°C), or higher power rating (0.13W), maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Select RG1005P-2372-B-T5 (Susumu) when packaging format change from bulk to Tape & Reel is acceptable. This part maintains all electrical and mechanical specifications of the obsolete RG1005P-2372-B-T1 while offering active product status and improved supply availability.

For Automotive AEC-Q200 Compliance Requirement:

When automotive qualification is mandatory, select from:

• RG1005P-2372-B-T5 (Susumu) - Direct equivalent with AEC-Q200 rating
• RG1005N-2372-B-T5 (Susumu) - Enhanced temperature coefficient (±10ppm/°C) with AEC-Q200 rating
• RG1005N-2372-W-T1 (Susumu) - Tighter tolerance (±0.05%) with AEC-Q200 rating
• RG1005P-2372-W-T5 (Susumu) - Tighter tolerance (±0.05%) with AEC-Q200 rating
• ERA-2AEB2372X (Panasonic) - Alternative manufacturer with AEC-Q200 rating
• TNPW040223K7BEED (Vishay Dale) - Enhanced power rating (0.13W) with AEC-Q200 rating

For Non-Automotive Applications:

When AEC-Q200 certification is not required:

• RT0402BRD0723K7L (YAGEO) - Highest inventory availability (29,358 pcs), identical electrical specifications
• CPF0402B23K7E1 (TE Connectivity) - High inventory (2,765 pcs), identical electrical specifications

For Extended Temperature Range Applications:

Select TNPW040223K7BEED (Vishay Dale) when operating temperature extends to 175°C. This part provides enhanced thermal capability while maintaining all other specifications.

For Precision-Critical Applications:

Select RG1005N-2372-W-T1 or RG1005P-2372-W-T5 (Susumu) when tolerance tighter than ±0.1% is required. Both parts offer ±0.05% tolerance with AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-2372-B-T5 be used as a direct replacement for RG1005P-2372-B-T1?

A: Yes. RG1005P-2372-B-T5 is electrically and mechanically identical to RG1005P-2372-B-T1. The only difference is packaging format: RG1005P-2372-B-T5 is supplied in Tape & Reel format while RG1005P-2372-B-T1 was supplied in bulk. Both parts share identical resistance (23.7 kOhms), tolerance (±0.1%), power rating (0.063W), temperature coefficient (±25ppm/°C), and AEC-Q200 qualification.

Q: What is the difference between RG1005P and RG1005N series?

A: The RG1005N series offers a tighter temperature coefficient (±10ppm/°C) compared to RG1005P series (±25ppm/°C). Both series maintain identical resistance values, tolerance options, and package specifications. RG1005N is suitable for applications requiring superior temperature stability.

Q: What does the "W" designation in part numbers RG1005N-2372-W-T1 and RG1005P-2372-W-T5 indicate?

A: The "W" designation indicates tighter tolerance specification of ±0.05% compared to the standard ±0.1% tolerance (indicated by "B" designation). Both W and B variants are available in the same package and power rating.

Q: Is TNPW040223K7BEED compatible with the original RG1005P-2372-B-T1?

A: TNPW040223K7BEED is compatible with enhanced specifications. It maintains the same resistance (23.7 kOhms), tolerance (±0.1%), package (0402), and temperature coefficient (±25ppm/°C). However, it offers higher power rating (0.13W vs. 0.063W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). This part is suitable for applications requiring higher power dissipation capability.

Q: Why does MCS04020D2372BE100 have a lower maximum operating temperature (125°C vs. 155°C)?

A: MCS04020D2372BE100 from Vishay Beyschlag is rated to 125°C maximum, which is lower than the original RG1005P-2372-B-T1 specification of 155°C. This part is not suitable for applications requiring operation above 125°C. Verify application temperature requirements before selection.

Q: Which substitute part has the highest inventory availability?

A: RT0402BRD0723K7L (YAGEO) has the highest inventory with 29,358 pieces in stock. This part maintains identical electrical specifications (23.7 kOhms, ±0.1%, 0.063W, ±25ppm/°C) and is suitable for non-automotive applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), matching the original RG1005P-2372-B-T1 specifications.

Q: Can I use RT0402BRD0723K7L or CPF0402B23K7E1 in automotive applications?

A: RT0402BRD0723K7L (YAGEO) and CPF0402B23K7E1 (TE Connectivity) do not carry AEC-Q200 automotive qualification. For automotive applications, use parts with explicit AEC-Q200 rating: RG1005P-2372-B-T5, RG1005N-2372-B-T5, RG1005N-2372-W-T1, RG1005P-2372-W-T5, ERA-2AEB2372X, or TNPW040223K7BEED.

Q: What is the physical size difference between substitute parts?

A: All substitute parts use the same 0402 (1005 Metric) package with dimensions 0.039" L x 0.020" W (1.00mm x 0.50mm). Height varies slightly: most parts have maximum seated height of 0.016" (0.40mm), while RT0402BRD0723K7L and CPF0402B23K7E1 have 0.014" (0.35mm) maximum height. These minor height variations are within standard PCB assembly tolerances.
