Engineering Selection Recommendations

Primary Substitutes (Closest Mechanical Match):

PBC36SAAN and PEC36SAAN from Sullins Connector Solutions are the closest mechanical equivalents to the 94549-136H. Both maintain identical contact length specifications (0.230" mating, 0.120" post), insulation height (0.100"), and overall contact length (0.450"). These parts are ROHS3 compliant and rated for -65°C to 125°C operation with 3A current capacity. PBC36SAAN features gold mating finish while PEC36SAAN uses tin finish. Both are suitable for direct substitution in applications where RoHS compliance is required.

Extended Post Length Options:

PBC36SABN and PEC36SABN provide extended post length (0.230" vs. 0.120") for applications requiring deeper PCB penetration or additional mechanical support. These variants maintain all other mechanical parameters identical to their shorter-post counterparts and are ROHS3 compliant.

TE Connectivity Alternative:

8-146274-6 from TE Connectivity AMPMODU Mod II series offers breakaway capability and is RoHS compliant. Note that insulation height is 0.090" (2.29mm) versus the standard 0.100", and contact length mating is 0.318" (8.08mm) versus 0.230". These dimensional differences may affect compatibility with existing mating connectors. Operating temperature range is -65°C to 105°C with 3A current rating.

Samtec TSW Series Options:

Samtec TSW-136 series headers provide variable post lengths (0.400", 0.500", 0.600") for applications requiring extended through-hole engagement. Available in gold (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S) and tin (TSW-136-09-T-S, TSW-136-10-T-S) finishes. Operating temperature ranges from -55°C to 125°C (gold) or -55°C to 105°C (tin). All TSW variants are ROHS3 compliant with MSL 1 rating.

RoHS Compliance Consideration:

The original 94549-136H is RoHS non-compliant. All listed substitutes are RoHS compliant (RoHS or ROHS3). Design specifications requiring RoHS non-compliant components must be evaluated separately.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 94549-136H with any of these parts directly?

A: Direct substitution depends on your specific application requirements. All listed parts share the same mating pitch (0.100"), position count (36), and contact geometry (square male pins). However, variations in post length, contact finish, and insulation material may affect compatibility with existing mating connectors or PCB stack-up. Verify that the substitute part's overall contact length and insulation height match your application's mechanical constraints.

Q: What is the difference between gold and tin contact finishes?

A: Contact finish affects corrosion resistance and environmental performance. Gold finish (used in 94549-136H, PBC36SAAN, PBC36SABN, TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S) provides superior corrosion resistance and is preferred for harsh environments or long-term storage. Tin finish (used in PEC36SAAN, PEC36SABN, TSW-136-09-T-S, TSW-136-10-T-S) is cost-effective and suitable for standard applications with normal environmental exposure. Both finishes are electrically equivalent for mating purposes.

Q: Why do some substitutes have different post lengths?

A: Post length determines how far the contact extends into the PCB. Shorter posts (0.085" to 0.120") are suitable for standard PCB thicknesses. Extended posts (0.230" to 0.600") accommodate thicker PCBs, multiple stacked boards, or applications requiring additional mechanical support. Select post length based on your PCB thickness and assembly requirements.

Q: Are the Samtec TSW-136 series compatible with the 94549-136H?

A: TSW-136 series parts are mechanically compatible at the mating interface (same pitch, position count, and contact geometry). However, they feature significantly longer posts (0.400" to 0.600" versus 0.085" to 0.120" in the original). This extended length may not be suitable for standard PCB applications and should be verified against your specific board design.

Q: What does RoHS compliance mean for this connector?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the part does not contain restricted materials such as lead, cadmium, or hexavalent chromium. The original 94549-136H is RoHS non-compliant, while all listed substitutes are RoHS or ROHS3 compliant. If your application or region requires RoHS compliance, select from the compliant alternatives.

Q: Can I use the TE Connectivity 8-146274-6 as a direct replacement?

A: The 8-146274-6 is functionally compatible but has dimensional differences: insulation height is 0.090" (versus 0.100") and contact length mating is 0.318" (versus 0.230"). These differences may affect fit with existing mating connectors. Verify compatibility with your mating connector specifications before substitution.

Q: What is the difference between breakaway and non-breakaway headers?

A: Breakaway headers (PBC36SAAN, PBC36SABN, PEC36SAAN, PEC36SABN, 8-146274-6) allow individual pins or groups of pins to be separated after assembly, providing flexibility for custom configurations. Non-breakaway headers (94549-136H, TSW-136 series) maintain all 36 positions as a single unit. Select based on whether your application requires individual pin separation capability.

Q: How do I determine which substitute is best for my application?

A: Prioritize based on: (1) Mating interface compatibility (verify contact length and insulation height match your mating connector), (2) Post length requirements (based on PCB thickness), (3) Environmental requirements (operating temperature, contact finish for corrosion resistance), (4) Compliance requirements (RoHS status), and (5) Availability and cost. Consult your mating connector specifications and PCB design requirements before final selection.
