Key Parameters

Substitute Part Grouping Explanation

Substitution of the BD13616S is determined by electrical and mechanical parameter equivalence. All substitute parts must satisfy the following criteria:

Electrical Parameters (Required Match):

• Transistor Type: PNP
• Voltage - Collector Emitter Breakdown (Max): 45 V
• Current - Collector (Ic) (Max): 1.5 A
• Power - Max: 1.25 W
• Vce Saturation (Max) @ Ib, Ic: 500mV @ 50mA, 500mA
• Current - Collector Cutoff (Max): 100nA (ICBO)
• DC Current Gain (hFE) (Min) @ Ic, Vce: minimum 40 @ 150mA, 2V

Mechanical Parameters (Required Match):

• Mounting Type: Through Hole
• Package / Case: TO-225AA or TO-126-3 compatible

Substitute parts are grouped into two categories: direct equivalents with identical package designation and compatible alternatives with functionally equivalent packages.

Engineering Selection Recommendations

Direct Equivalent (Preferred for Pin-Compatible Replacement):

BD13616STU (Fairchild Semiconductor) is the direct equivalent substitute. This part maintains identical electrical specifications and TO-126-3 package configuration. The device is in Active product status with 17,385 pieces in stock, providing immediate availability. This part is suitable for direct board-level substitution without layout modifications.

Primary Alternative (onsemi Source):

BD136G (onsemi) is an active production alternative from the same manufacturer as the original part. It maintains all critical electrical parameters and operates within the same temperature range. The TO-126 package is mechanically compatible with TO-126-3 applications. This option provides continuity with the original manufacturer while ensuring long-term availability.

Secondary Alternatives (STMicroelectronics Source):

BD136 and BD136-16 (STMicroelectronics) are functionally equivalent alternatives with different package designations (SOT-32-3 and SOT-32 respectively). These parts meet all electrical requirements but require PCB layout verification due to package differences. Both devices are in Active status with substantial inventory levels. Selection between these variants depends on existing board design constraints and package footprint compatibility.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original BD13616S. The ECCN classification (EAR99) and HTSUS code (8541.29.0095) remain unchanged across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can BD13616STU be used as a direct replacement for BD13616S?

A: Yes. BD13616STU is electrically and mechanically equivalent to BD13616S. Both devices feature identical electrical specifications, Vce saturation characteristics, and TO-126-3 package configuration. No circuit modifications or board layout changes are required.

Q: What is the difference between BD136G and BD136-16?

A: BD136G is supplied in TO-126 package format, while BD136-16 is supplied in SOT-32 package format. Both devices meet identical electrical specifications. Package selection depends on PCB footprint availability and design requirements. The TO-126 variant (BD136G) is more closely aligned with the original BD13616S package family.

Q: Are there DC current gain differences between substitute parts?

A: Yes. BD13616S specifies a minimum DC current gain (hFE) of 100 @ 150mA, 2V. BD13616STU maintains this specification. BD136G, BD136, and BD136-16 specify a minimum hFE of 40 @ 150mA, 2V. This lower specification is within acceptable substitution parameters for most applications but should be verified against circuit design requirements if gain-dependent biasing is employed.

Q: Which substitute part offers the best long-term availability?

A: BD13616STU (Fairchild Semiconductor) and BD136G (onsemi) both offer Active product status with high inventory levels (17,385 and 16,536 pieces respectively). BD136G provides continuity with the original manufacturer. Both parts are suitable for long-term production commitments.

Q: Do package differences affect thermal performance?

A: All substitute parts are rated for identical maximum power dissipation (1.25 W) and maximum operating temperature (150°C TJ). Package differences (TO-126-3, TO-126, SOT-32-3, SOT-32) do not alter thermal specifications. Thermal performance depends on PCB layout, copper area, and heat sinking implementation rather than package designation.

Q: Are all substitute parts RoHS compliant?

A: BD13616STU compliance status is not specified in available documentation. BD136G, BD136, and BD136-16 are all ROHS3 compliant. Compliance verification with BD13616STU should be obtained from Fairchild Semiconductor if RoHS certification is a design requirement.

Q: Can SOT-32 packaged parts (BD136, BD136-16) be used on TO-126-3 PCB layouts?

A: No. SOT-32 and TO-126-3 packages have different pin configurations and footprints. PCB layout modifications are required to accommodate SOT-32 packaged devices. TO-126 packaged parts (BD136G) are mechanically compatible with TO-126-3 layouts and do not require board redesign.
