• Fastening Type: Push-Pull and Latch Holder are both acceptable

The substitute parts identified below maintain all critical matching parameters while offering active product status and compliance certifications equivalent to the original component.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements, providing continuity for designs currently utilizing the obsolete TE Connectivity 1-1734493-0.

Molex Milli-Grid 87833 Series (0878331033, 0878331041, 0878331051): These parts are direct functional equivalents with identical pitch, position count, and mounting configuration. All three variants are active products with extended operating temperature range (-55°C to 105°C). The primary distinction lies in fastening type: 0878331033 retains push-pull fastening identical to the original, while 0878331041 and 0878331051 employ latch holder fastening. Contact material is phosphor bronze rather than brass, and insulation material is glass-filled polyamide (PA46) rather than standard polyamide (PA6T). All three carry UL94 V-0 flammability rating and ROHS3 compliance. Packaging options include tube (0878331033, 0878331041) and tape & reel (0878331051).

Samtec Flex Stack LTMM Series (LTMM-105-02-S-D-RA, LTMM-105-02-T-D-RA): These parts maintain all critical electrical and mechanical parameters with active product status. Both variants feature liquid crystal polymer (LCP) insulation material and phosphor bronze contacts. The primary distinction is contact finish: LTMM-105-02-S-D-RA provides gold mating finish, while LTMM-105-02-T-D-RA provides tin mating finish. Both support extended operating temperature range (-55°C to 125°C for the S variant, -55°C to 105°C for the T variant). Flammability rating is not specified for these parts. Both carry ROHS3 compliance and are supplied in tube packaging.

Selection Criteria:

• For direct replacement with identical fastening mechanism: Select Molex 0878331033
• For extended temperature operation to 125°C: Select Samtec LTMM-105-02-S-D-RA
• For tape & reel packaging: Select Molex 0878331051
• For tin mating finish: Select Samtec LTMM-105-02-T-D-RA

Frequently Asked Questions (FAQ)

Q: Can the Molex 0878331033 be used as a direct replacement for the TE Connectivity 1-1734493-0?

A: Yes. The Molex 0878331033 maintains identical pitch (2.00mm), position count (10), row configuration (2 rows), mounting type (through-hole right-angle), shrouding (4-wall), termination (solder), and fastening type (push-pull). All critical electrical and mechanical parameters are equivalent. The primary differences are contact material (phosphor bronze vs. brass) and insulation material (glass-filled PA46 vs. PA6T), both of which are acceptable variations for this connector category.

Q: What is the difference between the Molex variants 0878331033, 0878331041, and 0878331051?

A: All three Molex parts share identical electrical and mechanical specifications. The differences are: (1) Fastening Type: 0878331033 uses push-pull fastening (matching the original), while 0878331041 and 0878331051 use latch holder fastening; (2) Packaging: 0878331033 and 0878331041 are supplied in tube packaging, while 0878331051 is supplied in tape & reel format; (3) Inventory availability varies by part number.

Q: Are the Samtec LTMM parts compatible with the original TE Connectivity connector?

A: The Samtec LTMM-105-02-S-D-RA and LTMM-105-02-T-D-RA maintain all critical mating parameters (pitch, position count, row spacing, mounting type, shrouding, and termination). However, contact length differs slightly (0.120" vs. 0.141" mating contact length), and insulation material is liquid crystal polymer rather than polyamide. These parts are functionally compatible for board-to-board applications but may require mechanical validation in space-constrained designs.

Q: What is the significance of contact finish differences between parts?

A: Contact finish affects corrosion resistance and mating force characteristics. The original TE part specifies gold mating finish (10.0µin thickness). Molex substitutes provide gold finish (15.0µin thickness), offering enhanced corrosion protection. The Samtec LTMM-105-02-T-D-RA provides tin mating finish, which is acceptable for general-purpose applications but may exhibit different wear characteristics in high-cycle mating scenarios.

Q: Can I use a part with latch holder fastening instead of push-pull fastening?

A: Latch holder fastening (Molex 0878331041, 0878331051) provides positive mechanical retention compared to push-pull fastening. Substitution is permissible if the mating connector is compatible with latch holder engagement. Verify mating connector specifications before substitution.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (Molex 0878331033, 0878331041; Samtec LTMM variants) is suitable for manual assembly and lower-volume production. Tape & reel packaging (Molex 0878331051) is optimized for automated pick-and-place assembly equipment. Selection depends on manufacturing process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, maintaining regulatory equivalence with the original TE Connectivity 1-1734493-0.

Q: What is the operating temperature range difference, and does it matter?

A: The original TE part operates from -40°C to 105°C. Molex substitutes extend the lower limit to -55°C. Samtec LTMM-105-02-S-D-RA extends the upper limit to 125°C. Extended temperature ranges provide design margin for applications with extreme environmental conditions but are not required for standard -40°C to 105°C operation.
