Phoenix Contact 1924596 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1924596 is a 9-position terminal block header with male pins, shrouded on 4 sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON MSTBV series and is actively manufactured. Terminal block headers are essential interconnection components in industrial control systems, power distribution panels, and modular electronic assemblies where reliable, field-serviceable connections are required. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and compatibility with existing connector ecosystems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block headers is determined by strict alignment of electrical and mechanical parameters. The primary criteria for equivalence are:

• Position Count & Pitch: Both main and substitute parts must have identical 9-position configuration at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
• Pin Configuration: Both parts feature male pins with 4-side shrouding, ensuring identical mating interface geometry.
• Mounting & Termination: Vertical through-hole solder termination is consistent across both parts, allowing direct PCB substitution.
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements. The substitute part (Molex 0395355009) carries UL ratings of 15 A at 300 V, which is compatible with the main part's 16 A at 300 V specification for most industrial applications.
• Material & Compliance: Both parts use polyamide nylon housing with UL94 V-0 flammability rating and RoHS compliance, ensuring regulatory and safety equivalence.
• Contact Finish & Geometry: Tin-plated contacts and comparable insulation heights (0.472") ensure reliable mating and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1924596 and Molex 0395355009 are active, RoHS-compliant products with UL94 V-0 flammability certification, making them suitable for equivalent application in industrial control and power distribution environments. The Molex substitute carries a 15 A UL current rating compared to the Phoenix Contact's 16 A rating; this 1 A difference is negligible for most standard applications and does not compromise functional equivalence. Both parts maintain identical voltage ratings (300 V UL), pitch geometry (5.08mm), and mounting configuration, ensuring direct PCB-level substitution without design modification. Contact tail length variance (3.90mm vs. 3.81mm) is within typical manufacturing tolerance and does not affect solder joint reliability or mechanical fit. Selection between these parts should be based on supply availability, lead time, and cost considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395355009 be used as a direct replacement for the Phoenix Contact 1924596 on existing PCBs?

A: Yes. Both parts share identical 9-position configuration, 5.08mm pitch, vertical through-hole solder termination, and shrouded male pin geometry. PCB footprints and mating connector compatibility are equivalent. No design changes are required.

Q: What is the significance of the 1 A current rating difference (16 A vs. 15 A)?

A: The Phoenix Contact part is rated for 16 A (UL) while the Molex substitute is rated for 15 A (UL). This difference is within typical industrial application margins. For applications requiring the full 16 A capacity, the Phoenix Contact part should be specified. For applications operating below 15 A, either part is suitable.

Q: Are the housing materials functionally equivalent?

A: Both parts use polyamide nylon housing with UL94 V-0 flammability rating. The Phoenix Contact uses PA nylon while the Molex uses PA66 (Nylon 6/6). Both materials provide equivalent electrical insulation, mechanical strength, and thermal performance for this application category.

Q: Does the contact tail length difference affect PCB assembly?

A: The contact tail length variance (3.90mm vs. 3.81mm) is 0.09mm and falls within standard PCB through-hole tolerance. This difference does not affect solder joint formation, mechanical retention, or electrical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the Phoenix Contact 1924596 and Molex 0395355009 are RoHS compliant with tin-plated contact finishes, meeting EU and international environmental regulations.

Q: What is the operating temperature range for these parts?

A: The Molex 0395355009 specifies an operating temperature range of -40°C to 115°C. The Phoenix Contact 1924596 does not provide an explicit operating temperature specification in the available data. For applications with specific temperature requirements, verify compatibility with the Molex specification or contact the manufacturer.
