Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0878980865 is determined by strict equivalence in the following parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 8
• Number of Rows: 1
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.320" (8.13mm)
• Contact Shape: Square
• Style: Board to Board or Cable
• Shrouding: Unshrouded
• Material Flammability Rating: UL94 V-0
• RoHS Status: RoHS3 Compliant

The Samtec TSM series connectors meet all these core electrical and mechanical requirements. Variations among substitute parts exist in contact material composition, insulation material type, contact finish specifications, operating temperature ranges, packaging format, and connector style (cuttable vs. breakaway). These variations do not affect functional interchangeability for standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

All listed Samtec TSM-108 variants are Active status products with RoHS3 compliance and REACH Unaffected designation, matching the regulatory compliance profile of the Molex 0878980865.

Selection among substitute parts depends on specific application requirements:

For gold-plated mating contacts: TSM-108-02-L-SV, TSM-108-02-L-SV-P-TR, and TSM-108-02-S-SV maintain gold contact finish specifications. TSM-108-02-L-SV-P-TR and TSM-108-02-L-SV-P-TR include Pick and Place features suitable for automated assembly.

For tin-plated mating contacts: TSM-108-02-T-SV, TSM-108-02-T-SV-P-TR, and TSM-108-02-TM-SV provide tin contact finish. These variants operate at -55°C to 105°C, compared to the higher temperature capability of gold-plated variants at -55°C to 125°C.

For packaging format: Tube packaging is available in TSM-108-02-L-SV, TSM-108-02-S-SV, TSM-108-02-T-SV, and TSM-108-02-TM-SV. Tape & Reel packaging is available in TSM-108-02-L-SV-P-TR and TSM-108-02-T-SV-P-TR for high-volume automated production.

For connector style: All Samtec variants feature cuttable design, whereas the Molex part features breakaway design. Both styles maintain functional compatibility for board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Are all listed Samtec parts electrically and mechanically compatible with the Molex 0878980865?

A: Yes. All substitute parts share identical pitch (0.100"), position count (8), row configuration (1), contact type (male pin), mounting method (surface mount), termination (solder), and fastening type (push-pull). Mating contact length and shape are identical across all parts.

Q: What is the difference between breakaway and cuttable connector styles?

A: Breakaway connectors feature pre-scored sections that separate cleanly at defined break points. Cuttable connectors allow custom separation at any position along the connector strip. Both styles are functionally compatible for standard 8-position applications.

Q: Does the difference in insulation material affect compatibility?

A: The Molex part uses polyamide (PA) nylon with glass fill, while Samtec variants use Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements and are suitable for the same application categories. Material selection does not affect electrical or mechanical mating characteristics.

Q: What is the significance of contact finish differences?

A: The Molex part features gold-plated mating contacts (30.0µin thickness) with tin-plated posts. Samtec gold-plated variants (TSM-108-02-L-SV, TSM-108-02-L-SV-P-TR, TSM-108-02-S-SV) provide equivalent gold finish specifications. Tin-plated variants (TSM-108-02-T-SV, TSM-108-02-T-SV-P-TR, TSM-108-02-TM-SV) use tin for mating contacts. Contact finish selection depends on application corrosion resistance requirements and environmental exposure.

Q: Why do some Samtec variants have lower operating temperature ratings?

A: Tin-plated contact variants (TSM-108-02-T-SV, TSM-108-02-T-SV-P-TR, TSM-108-02-TM-SV) are rated to -55°C to 105°C, while gold-plated variants extend to -55°C to 125°C. Application temperature requirements should determine variant selection.

Q: What packaging options are available?

A: Tube packaging is standard for most variants. Tape & Reel (TR) packaging is available for TSM-108-02-L-SV-P-TR and TSM-108-02-T-SV-P-TR, designed for automated pick-and-place assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed Samtec variants are RoHS3 compliant and REACH Unaffected, matching the regulatory status of the Molex 0878980865.
