Phoenix Contact 1829920 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1829920 is a 4-position terminal block header with male pins, shrouded on all four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 12A (IEC) / 12A (UL) and 200V (IEC) / 300V (UL), utilizing press-fit termination technology within the COMBICON EMSTBVA series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1829920 is determined by the following critical parameters:

• Position Count: Must be 4 positions to maintain PCB layout compatibility
• Pitch: Must be 0.200" (5.08mm) to ensure connector mating compatibility
• Header Orientation: Must be vertical for through-hole mounting alignment
• Shrouding: Must be shrouded on 4 sides for mechanical protection and polarization
• Mounting Type: Must be through-hole to match existing PCB footprints
• Electrical Ratings: Must meet or exceed 12A current and 200V (IEC) / 300V (UL) voltage requirements
• Contact Tail Length: 0.154" (3.90mm) is the reference dimension for PCB hole depth compatibility

Two substitute parts are identified from the Phoenix Contact product line. The primary substitute (1936034) maintains identical position count and pitch specifications with enhanced electrical performance. The secondary substitute (1956137) differs in position count and is suitable only for applications requiring expanded connectivity within the same pitch and mounting architecture.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1936034

Part 1936034 is the direct functional equivalent for applications requiring 4-position terminal block headers at 0.200" (5.08mm) pitch. This part is active in production status, ensuring long-term availability and supply chain stability. The electrical ratings (12A IEC, 400V IEC, 12A UL, 300V UL) exceed the original part specifications, providing enhanced performance margin. The transition from press-fit to solder termination requires PCB design modification but offers improved mechanical reliability. Material compliance includes UL94 V-0 flammability rating and RoHS3 compliance, meeting current regulatory requirements. Housing material is Polybutylene Terephthalate (PBT), and the part includes a locking ramp feature for enhanced connector retention.

Secondary Substitute: Phoenix Contact 1956137

Part 1956157 is suitable only for applications where expanded connectivity (7 positions) is acceptable within the existing 0.200" (5.08mm) pitch architecture. This part is active in production status. The electrical ratings (12A per position IEC, 400V IEC, 10A UL, 300V UL) meet or exceed the original part requirements on a per-position basis. The contact tail length (0.102" / 2.60mm) differs from the original part and requires PCB hole depth verification. Housing material is Liquid Crystal Polymer (LCP), and the part includes a locking ramp feature. RoHS compliance is confirmed. This substitute is applicable only when circuit design permits the increased position count and the shorter contact tail length is compatible with PCB specifications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1936034 be used as a direct replacement for 1829920?

A: Part 1936034 maintains identical position count (4), pitch (0.200" / 5.08mm), header orientation (vertical), shrouding (4 side), and mounting type (through hole). The primary difference is termination style: 1936034 uses solder termination instead of press-fit. PCB design modification is required to accommodate solder pads instead of press-fit holes. Electrical ratings are superior, and the part is in active production status.

Q: What is the key difference between 1936034 and 1956137?

A: The primary difference is position count: 1936034 provides 4 positions (direct equivalent to 1829920), while 1956137 provides 7 positions. Additionally, 1956137 has a shorter contact tail length (0.102" versus 0.154"), which may affect PCB hole depth compatibility. Both parts share the same 0.200" (5.08mm) pitch and vertical orientation.

Q: Does the contact tail length difference in 1956137 affect compatibility?

A: Yes. The contact tail length of 1956137 (0.102" / 2.60mm) is shorter than the original part (0.154" / 3.90mm). PCB hole depth and solder fillet clearance must be verified before implementation. This dimension difference may require PCB redesign.

Q: Are there compliance or certification differences between the substitute parts?

A: Part 1936034 carries UL94 V-0 flammability rating and RoHS3 compliance. Part 1956137 carries UL94 V-0 flammability rating and RoHS compliance. Both parts are EAR99 classified and share the same HTSUS code (8536.69.4040) as the original part.

Q: What is the impact of changing from press-fit to solder termination?

A: Press-fit termination (1829920) requires precision-drilled holes with specific tolerances and uses mechanical insertion. Solder termination (1936034) requires PCB pads designed for wave or reflow soldering. The transition requires PCB layout modification but offers improved mechanical reliability and is standard in current manufacturing processes.

Q: Can 1956137 be used if only 4 positions are needed?

A: Part 1956137 is a 7-position header. While it can be physically mounted on a PCB designed for 4 positions, only 4 positions would be utilized, leaving 3 positions unused. This approach is inefficient and not recommended. Use 1936034 for 4-position applications.
