Phoenix Contact 1914878 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1914878 is a 4-position terminal block header with male pins, shrouded design, and 0.197" (5.00mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 12A current (IEC/UL) and 320V (IEC) / 300V (UL) voltage ratings, with press-fit termination and UL94 V-0 flammability compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914878 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Pitch: 0.197" (5.00mm)
• Header Orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting Type: Through Hole
• Current Rating (IEC): 12A
• Voltage Rating (IEC): 320V minimum
• Contact Tail Length: 0.154" (3.90mm)
• Insulation Height: 0.472" (12.00mm)
• Contact Mating Finish: Tin

Allowable Variations:

• Termination Style: Press-Fit or Solder acceptable
• Housing Material: PBT or Polyamide (PA) acceptable
• Product Status: Active substitutes preferred for obsolete main part
• RoHS Compliance: RoHS3 acceptable for RoHS Compliant main part

The two identified substitutes (1755532 and 1837048) meet all mandatory parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1755532

Part 1755532 is the preferred substitute for the obsolete 1914878. It maintains all critical electrical and mechanical parameters including 4-position configuration, 5.00mm pitch, vertical orientation, and 12A/320V (IEC) ratings. The transition from press-fit to solder termination requires PCB design modification but is a standard engineering practice. Housing material change from PBT to Polyamide (PA) is acceptable within the COMBICON product family. The part carries active product status with ROHS3 compliance and significantly higher inventory availability (5009 units), ensuring supply chain continuity.

Secondary Substitute: Phoenix Contact 1837048

Part 1837048 serves as an alternative substitute with matching core parameters (4-position, 5.00mm pitch, vertical through-hole, 12A current, 320V IEC voltage). However, incomplete specification data for UL ratings, contact tail length, insulation height, housing material, and flammability rating limits its direct equivalency assessment. This part is suitable only when complete technical documentation confirms compatibility with application requirements.

Compliance Considerations:

Both substitutes provide ROHS3 compliance, exceeding the RoHS Compliant status of the main part. The 1755532 maintains UL94 V-0 flammability rating and full electrical specifications. Selection should prioritize 1755532 for applications requiring complete specification transparency and established compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1755532 directly replace 1914878 in existing designs?

A: Direct PCB replacement requires modification of the termination footprint. The 1914878 uses press-fit termination while 1755532 uses solder termination. Mechanical fit (pitch, position count, orientation, tail length, insulation height) is identical, but PCB pad design and assembly process must be updated accordingly.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination uses mechanical insertion into plated through-holes without solder. Solder termination requires molten solder connection to PCB pads. Solder termination is the industry standard for high-volume production and provides superior mechanical reliability in vibration-prone applications.

Q: Are the housing material differences between 1914878 (PBT) and 1755532 (Polyamide) significant?

A: Both materials meet UL94 V-0 flammability requirements and are standard within the COMBICON terminal block family. Polyamide offers slightly higher temperature capability and chemical resistance. For standard industrial applications, both materials are functionally equivalent.

Q: Why is 1837048 listed as a substitute if specification data is incomplete?

A: Part 1837048 meets all mandatory electrical and mechanical parameters (4-position, 5.00mm pitch, vertical orientation, 12A current, 320V IEC voltage, tin finish). However, missing UL ratings and dimensional confirmation data prevents full equivalency validation. Use this part only after confirming complete specifications with Phoenix Contact technical documentation.

Q: What is the inventory status for these substitutes?

A: The 1914878 (obsolete) has 891 units available. The 1755532 (active) has 5009 units in stock, providing superior supply security. The 1837048 (active) has 959 units available. For new designs, 1755532 is recommended due to higher inventory levels and active product status.

Q: Are all three parts RoHS compliant?

A: Yes. The 1914878 is RoHS Compliant. Both 1755532 and 1837048 are ROHS3 Compliant, which represents an enhanced compliance standard. All three parts meet RoHS requirements for new applications.
