Substitute Part Grouping Explanation

Substitution of the 68730-336 is determined by strict equivalence across the following critical parameters:

Connector Type & Configuration: Header, male pin, 36 positions, single row
Pitch Specification: 0.100" (2.54mm) mating pitch
Mounting & Termination: Through-hole solder termination with push-pull fastening
Contact Geometry: Square contact shape with 0.230" (5.84mm) mating contact length
Electrical & Mechanical Compliance: UL94 V-0 flammability rating, MSL 1 classification

All identified substitute parts maintain these core parameters. Variations in contact post length, insulation material composition, contact finish specifications, and operating temperature ranges are secondary design parameters that do not preclude functional substitution in standard applications.

Engineering Selection Recommendations

All identified substitute parts maintain functional equivalence to the 68730-336 across core connector specifications. Selection among active alternatives should prioritize the following criteria:

RoHS Compliance: The original 68730-336 is RoHS non-compliant. All substitute parts listed are RoHS compliant (RoHS3 or RoHS Compliant), making them suitable for applications subject to regulatory compliance requirements.

Product Status: The 68730-336 is obsolete. All substitute parts maintain active product status with established supply chains and manufacturing continuity.

Contact Post Length Variation: Substitute parts offer contact post lengths ranging from 0.100" to 0.900". Selection should align with PCB thickness and application requirements. The 8-146274-6, HTSW-136-26-TM-S, and PGC36SAAN provide post lengths closest to the original specification (0.125" to 0.120").

Contact Finish Options: Gold-finished variants (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, TSW-136-13-F-S, PGC36SAAN) provide corrosion resistance comparable to the original gold finish. Tin-finished variants (8-146274-6, HTSW-136-26-TM-S, TSW-136-09-T-S, TSW-136-10-T-S) offer cost optimization for non-corrosive environments.

Operating Temperature Range: Samtec TSW series parts support -55°C to 125°C operation, exceeding the original specification. TE Connectivity 8-146274-6 supports -65°C to 105°C. HTSW-136-26-TM-S supports -55°C to 105°C. These ranges accommodate extended thermal requirements.

Insulation Material: Samtec TSW series utilizes Polybutylene Terephthalate (PBT), TE Connectivity 8-146274-6 uses Liquid Crystal Polymer (LCP), and HTSW-136-26-TM-S employs LCP. These materials maintain UL94 V-0 flammability compliance.

Frequently Asked Questions (FAQ)

Q: Can the 68730-336 be directly replaced with any of these substitute parts?

A: Yes. All substitute parts maintain the critical functional parameters: 36-position, 0.100" pitch, through-hole solder termination, push-pull fastening, and square contact geometry. Physical board layout compatibility depends on contact post length and insulation height, which are provided in the parameter comparison table.

Q: What is the primary reason for substitution?

A: The 68730-336 is classified as obsolete. Substitute parts are active products with established supply chains. Additionally, all substitutes are RoHS compliant, whereas the original part is RoHS non-compliant, making substitutes necessary for applications subject to regulatory requirements.

Q: How do contact post length variations affect compatibility?

A: Contact post length determines the effective engagement depth with mating connectors and PCB hole depth requirements. The original 68730-336 specifies 0.225" post length. Substitutes range from 0.100" to 0.900". For direct mechanical replacement, select parts with post lengths within ±0.050" of the original specification: 8-146274-6 (0.125"), HTSW-136-26-TM-S (0.126"), or PGC36SAAN (0.120").

Q: Are there differences in contact finish that affect electrical performance?

A: Contact finish affects corrosion resistance and contact resistance stability. Gold-finished parts (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, PGC36SAAN) provide superior corrosion resistance in humid or corrosive environments. Tin-finished parts (8-146274-6, HTSW-136-26-TM-S, TSW-136-09-T-S, TSW-136-10-T-S) are suitable for standard indoor applications. The original 68730-336 specifies gold finish with 50.0µin thickness; gold-finished substitutes provide equivalent or superior protection.

Q: What is the significance of RoHS compliance?

A: RoHS (Restriction of Hazardous Substances) compliance is mandatory for products sold in the European Union and increasingly required by global manufacturers. The 68730-336 is RoHS non-compliant. All substitute parts are RoHS compliant, ensuring regulatory compliance for new designs and procurement.

Q: Can I use a substitute part with a longer contact post in an existing design?

A: Longer contact posts increase overall connector height and may affect mating connector engagement. Verify that the mating connector accommodates the increased post length. Shorter post lengths may result in insufficient engagement depth. Consult mechanical drawings and mating connector specifications before selecting parts with post lengths differing significantly from the original 0.225" specification.

Q: Which substitute offers the best balance of cost and performance?

A: Cost and performance optimization depends on application requirements. The 8-146274-6 (TE Connectivity) offers extended operating temperature range (-65°C to 105°C) and LCP insulation material. The TSW-136-09-G-S (Samtec) provides the highest operating temperature (125°C) with gold finish. The PGC36SAAN (Sullins) offers gold finish with moderate post length (0.120"). Evaluate specific application thermal, environmental, and compliance requirements to determine optimal selection.

Q: Are all substitute parts available in the same packaging format?

A: Packaging varies by manufacturer. The 8-146274-6 and PGC36SAAN are supplied in bulk packaging. Samtec TSW series parts are supplied in bulk. HTSW-136-26-TM-S packaging is not specified. Confirm packaging requirements with procurement specifications before finalizing part selection.
