Molex 0908140018 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0908140018 is an 18-position surface mount header connector from the Picoflex PF-50 series, designed for board-to-cable/wire applications. This connector features a 0.050" (1.27mm) pitch, shrouded 2-wall design, and push-pull fastening. The part is currently obsolete, making identification of active equivalent and substitute parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0908140018 is determined by the following critical parameters:

Direct Equivalent (Same Series):

• Molex 0908140818 shares the identical base product number (090814), connector type (header), contact type (male blade), number of positions (18), pitch (0.050"/1.27mm), mounting type (surface mount), termination (solder), fastening type (push-pull), current rating (1.2A), voltage rating (250V), and material compliance (ROHS3, UL94 V-0). The primary difference is product status (active vs. obsolete) and insulation height (0.161" vs. 0.252"). This part is the direct active replacement.

Cross-Manufacturer Substitute (Different Pitch & Configuration):

• TE Connectivity 8-188275-8 is a receptacle connector from the Micro-MaTch series with 18 positions but operates at a different pitch (0.100"/2.54mm) and row configuration (2 rows vs. 1 row). This part is not a direct pin-compatible substitute due to pitch and contact type differences (forked receptacle vs. male blade header). Substitution requires circuit redesign and PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended): Molex 0908140818 is the active equivalent for the obsolete 0908140018. Both parts maintain identical electrical specifications (1.2A current rating, 250V voltage rating), mechanical compatibility (18 positions, 0.050" pitch, surface mount solder termination), and regulatory compliance (ROHS3, UL94 V-0). The insulation height difference (0.161" vs. 0.252") is a minor mechanical variation that does not affect electrical performance. This part has 4611 units in stock.

For Cross-Manufacturer Substitution (Design Modification Required): TE Connectivity 8-188275-8 requires circuit and PCB redesign due to fundamental differences: different pitch (0.100" vs. 0.050"), different row configuration (2 rows vs. 1 row), different contact type (forked receptacle vs. male blade header), and lower voltage rating (100VDC vs. 250V). This option is suitable only when design flexibility exists and the lower voltage rating is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can Molex 0908140818 be used as a direct drop-in replacement for 0908140018? A: Yes. Both parts share identical pitch (0.050"/1.27mm), position count (18), contact type (male blade), mounting type (surface mount), and electrical ratings (1.2A, 250V). The insulation height difference does not affect pin-to-pin compatibility or electrical performance.

Q: What is the primary reason for substituting the obsolete 0908140018? A: The 0908140018 is obsolete. Molex 0908140818 is the active production equivalent from the same series and manufacturer, ensuring continued supply and support.

Q: Is TE Connectivity 8-188275-8 pin-compatible with the Molex 0908140018? A: No. The TE part operates at 0.100" (2.54mm) pitch versus 0.050" (1.27mm), uses a 2-row configuration versus 1-row, and features forked receptacle contacts versus male blade headers. Pin-to-pin compatibility does not exist without PCB redesign.

Q: What are the key parameters that determine substitution eligibility? A: Pitch (0.050" for direct substitution), number of positions (18), connector type (header), contact type (male blade), mounting type (surface mount), and electrical ratings (1.2A, 250V) are the critical parameters. Deviation in any of these parameters requires design evaluation.

Q: Are both substitute parts RoHS and UL compliant? A: Yes. Molex 0908140818 and TE Connectivity 8-188275-8 are both ROHS3 compliant and carry UL94 V-0 material flammability ratings, matching the original part's compliance profile.

Q: What is the packaging difference between the main part and Molex 0908140818? A: The main part (0908140018) packaging is not specified. Molex 0908140818 is supplied in Tube packaging, which is standard for production quantities.
