Molex 0878030112 DDR2 SDRAM DIMM Socket - Equivalent & Substitute Parts

Part Overview

The Molex 0878030112 is a 240-position DIMM socket connector designed for DDR2 SDRAM memory modules. This through-hole mounted connector features board guide, board lock, and latch mechanisms for secure memory module retention. The part is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and legacy equipment support. Substitute parts must maintain identical electrical and mechanical specifications to ensure proper memory module compatibility and system performance.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1658912-2 is the qualified substitute for the obsolete Molex 0878030112. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The TE Connectivity part offers the advantage of active product status with current manufacturing availability (776 pcs in stock versus 669 pcs for the Molex part). Both parts carry ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and regulatory compliance. Selection of the TE Connectivity alternative eliminates obsolescence risk while maintaining full functional compatibility with DDR2 SDRAM memory modules and existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658912-2 be used as a direct replacement for the Molex 0878030112?

A: Yes. Both connectors match across all specified electrical and mechanical parameters, including 240-position DIMM configuration, DDR2 SDRAM memory type, 25° insertion angle, through-hole mounting, and identical contact finish specifications.

Q: What are the critical parameters that determine substitution compatibility?

A: The following parameters must match exactly: connector style (DIMM), number of positions (240), memory type (DDR2 SDRAM), mounting type (through hole), insertion angle (25°), card thickness (0.050"), contact finish (gold at 30.0µin), and mechanical features (board guide, board lock, latches).

Q: Does the TE Connectivity part have the same mounting footprint?

A: Yes. Both parts specify identical mounting features (normal, standard - top) and card thickness accommodation (0.050" / 1.27mm), ensuring compatible PCB layouts.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant with MSL 1 ratings. The TE Connectivity part maintains equivalent environmental and regulatory compliance.

Q: Why is the Molex part listed as obsolete?

A: The Molex 0878030112 has reached end-of-life status. The TE Connectivity 1658912-2 remains in active production, providing continued availability for new designs and legacy system support.
