Molex 0395211009 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Molex 0395211009 is a 9-position terminal block header with male pins, shrouded on four sides, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is classified as Active and is currently in stock with 1056 units available. Terminal block headers serve as connection interfaces in industrial control systems, power distribution modules, and signal routing applications where reliable solder termination and high current capacity are required. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and compliance certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395211009 is determined by the following critical parameters:

Position Count & Pitch Compatibility: The substitute must maintain 9 positions with pitch spacing within acceptable mechanical tolerance. The Molex part specifies 0.197" (5.00mm) pitch; the Phoenix Contact substitute operates at 0.200" (5.08mm) pitch, representing a 0.08mm variance. This minor pitch difference remains within standard PCB layout tolerances for through-hole terminal block applications.

Electrical Ratings: Both parts must support equivalent or superior current and voltage ratings. The Molex part is rated 15 A at 300 V (UL). The Phoenix Contact substitute provides 16 A at 300 V (UL), meeting or exceeding the original specification.

Mechanical Configuration: Both parts feature vertical orientation, male pins, four-sided shrouding, and solder termination on through-hole PCBs. Contact tail length and insulation height differ slightly but remain functionally compatible within standard assembly practices.

Compliance & Material Standards: Both parts carry UL94 V-0 flammability certification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring equivalent environmental and regulatory performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Molex 0395211009): Recommended when original design specifications require the exact 5.00mm pitch and 3.30mm contact tail length. Both parts maintain Active product status with full ROHS3 and UL94 V-0 compliance, ensuring long-term availability and regulatory alignment.

Substitute Selection (Phoenix Contact 1924376): Acceptable when PCB layout tolerances accommodate the 5.08mm pitch variant and 3.90mm contact tail length. The Phoenix Contact part provides equivalent electrical performance with a 1 A current rating advantage (16 A vs. 15 A). Both parts carry identical compliance certifications and moisture sensitivity ratings, supporting equivalent reliability in industrial environments.

Compatibility Consideration: The 0.08mm pitch difference and 0.60mm tail length variance require PCB footprint verification before design substitution. Standard through-hole assembly processes accommodate these minor dimensional variations without process modification.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1924376 be used as a direct replacement for Molex 0395211009?

A: Yes, with PCB footprint verification. Both parts share identical position count, orientation, shrouding configuration, and solder termination. The pitch difference (5.00mm vs. 5.08mm) and contact tail length variance (3.30mm vs. 3.90mm) fall within standard through-hole assembly tolerances. Confirm PCB pad spacing and via placement accommodate the Phoenix Contact dimensions before implementation.

Q: What are the critical electrical compatibility factors?

A: Both parts operate at 300 V (UL) with sufficient current capacity for the application. The Phoenix Contact substitute provides 16 A versus the Molex 15 A rating, exceeding the original specification. Voltage and current ratings are equivalent or superior, supporting direct electrical substitution.

Q: Are compliance certifications equivalent between the two parts?

A: Yes. Both parts carry UL94 V-0 flammability certification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Regulatory and environmental performance are identical, supporting equivalent use in certified applications.

Q: What is the impact of the pitch difference on assembly?

A: The 0.08mm pitch variance (5.00mm to 5.08mm) represents a 0.16% dimensional change across the 9-position span. Standard PCB manufacturing tolerances (±0.1mm) accommodate this variation. Verify PCB footprint design allows the slightly wider spacing before committing to production.

Q: Does the contact tail length difference affect solder joint quality?

A: The 0.60mm tail length increase (3.30mm to 3.90mm) provides additional solder fillet material, potentially improving joint reliability. This variance does not compromise assembly compatibility and may enhance mechanical strength in vibration-prone applications.
