Phoenix Contact 1937402 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1937402 is a 2-position terminal block header with male pins, shrouded on 4 sides, featuring a 0.138" (4.60mm) vertical pitch for through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance, mechanical compatibility, and mounting characteristics to ensure direct interchangeability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 2
• Pitch: 0.138" (4.60mm)
• Header Orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination Style: Solder
• Mounting Type: Through Hole
• Material Flammability Rating: UL94 V-0
• Contact Tail Length: 0.138" (4.60mm) or 0.134" (3.40mm)
• Insulation Height: 0.362" (9.20mm) or 0.360" (9.14mm)

Electrical Performance Parameters:

• Current - UL: 8 A minimum
• Voltage - UL: 300 V minimum
• Contact Mating Finish: Tin or Gold acceptable

Compliance Parameters:

• RoHS Status: ROHS3 Compliant or RoHS Compliant
• Material Flammability: UL94 V-0 required

All four substitute parts meet these criteria and are classified as active products, providing procurement alternatives to the obsolete 1937402.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1843224 is the primary substitute within the same manufacturer series (COMBICON MCV). This part maintains Phoenix Contact design continuity and is actively produced. The housing material differs (PBT versus glass-filled polyamide), and voltage rating is reduced to 250 V IEC, but UL ratings remain equivalent. This option is suitable for applications where manufacturer consistency is prioritized.

Molex 0395056002 and Molex 0395056502 are functionally equivalent alternatives from the Eurostyle ESE 39505 series. Both parts provide 8 A UL current rating and 300 V UL voltage rating. The 0395056502 variant features gold contact mating finish compared to tin on the 0395056002. Both are actively produced with defined operating temperature ranges (-40°C to 105°C). Housing material is PA66 nylon 6/6 in both cases.

Amphenol Anytek OQ0215500000G offers the highest current rating (10 A UL) among all substitutes, with extended operating temperature range (-40°C to 115°C). This part is suitable for applications requiring enhanced thermal performance or higher current capacity margins.

All substitute parts carry ROHS3 compliance and UL94 V-0 flammability ratings, meeting modern regulatory requirements. Selection should be based on specific application requirements, thermal environment, and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1937402 be directly replaced with any of these substitute parts?

A: Yes. All four substitute parts maintain the critical mechanical and electrical parameters: 2-position configuration, 0.138" (4.60mm) pitch, vertical orientation, through-hole solder termination, and UL94 V-0 flammability rating. Mechanical fit and electrical performance are preserved across all substitutes.

Q: What is the difference between the Molex 0395056002 and 0395056502?

A: Both parts are mechanically and electrically identical. The primary difference is the contact mating finish: 0395056002 uses tin finish, while 0395056502 uses gold finish. Gold finish provides enhanced corrosion resistance in certain environmental conditions.

Q: Does the contact tail length variation affect compatibility?

A: The main part 1937402 has a contact tail length of 0.134" (3.40mm), while all substitutes are 0.138" (4.60mm). This 0.004" (0.10mm) difference is within typical PCB pad tolerance and does not affect mechanical or electrical compatibility for standard through-hole solder applications.

Q: Which substitute offers the best thermal performance?

A: The Amphenol Anytek OQ0215500000G provides the highest operating temperature range (-40°C to 115°C) and the highest current rating (10 A UL). This part is optimal for applications in elevated temperature environments or where current margin is required.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts carry ROHS3 compliance status, meeting current environmental and regulatory requirements. The original 1937402 is RoHS compliant (earlier standard).

Q: What packaging options are available?

A: The main part 1937402 is listed with unspecified packaging. All substitute parts are available in bulk packaging, suitable for production assembly and component procurement workflows.
