Phoenix Contact 1879337 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1879337 is a 7-position terminal block header with male pins, featuring a shrouded 4-side design and 0.150" (3.81mm) vertical pitch. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL), with press-fit termination and through-hole mounting. Locating equivalent components ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1879337 is determined by the following critical parameters:

Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (250V IEC / 300V UL), and contact mating finish (Tin) must remain consistent.

Mechanical Compatibility: Number of positions (7), pitch (0.150" / 3.81mm), header orientation (Vertical), mounting type (Through Hole), shrouded design (4 Side), and housing material (PBT) must match.

Functional Compatibility: The substitute must maintain the same connector type classification (Header, Male Pins, Shrouded).

Compliance: RoHS3 compliance and UL94 V-0 flammability rating must be preserved.

The primary difference between the main part and its substitute lies in the termination style (Press-Fit vs. Solder) and contact tail length, which do not affect electrical or mechanical compatibility in the connector interface itself.

Engineering Selection Recommendations

The Phoenix Contact 1830648 serves as a direct functional equivalent to the 1879337. Both components share identical electrical ratings, mechanical dimensions (pitch, position count, orientation), housing material, and flammability certification. The 1830648 is currently in active production status, providing supply chain continuity for the obsolete 1879337.

The primary distinction is the termination method: the 1879337 uses press-fit termination, while the 1830648 employs solder termination. This difference requires PCB design modification to accommodate solder-based mounting instead of press-fit insertion. The contact tail length variance (0.150" vs. 0.138") reflects this termination style difference and does not affect connector interface compatibility.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability ratings, ensuring regulatory equivalence. Selection between these components depends on PCB design requirements and manufacturing process capabilities (press-fit vs. solder assembly).

Frequently Asked Questions (FAQ)

Q: Can the 1830648 directly replace the 1879337 without PCB modification?

A: Electrical and mechanical connector interface compatibility is maintained. However, PCB design modification is required due to termination style differences. The 1879337 uses press-fit termination (through-hole insertion), while the 1830648 requires solder termination. Pad layout and hole specifications must be adjusted accordingly.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components operate at 8A (IEC/UL) and 250V (IEC) / 300V (UL). Voltage and current handling capacity are equivalent.

Q: What is the significance of the contact tail length difference?

A: The contact tail length difference (0.150" vs. 0.138") is a direct result of the termination style change. Press-fit termination requires longer contact tails for insertion depth, while solder termination uses shorter tails for PCB pad engagement. This does not affect the mating interface between the header and its corresponding connector.

Q: Is the 1830648 suitable for new designs?

A: Yes. The 1830648 is in active production status and carries current regulatory certifications (ROHS3, UL94 V-0). It is appropriate for new product development requiring a 7-position, 3.81mm pitch terminal block header with vertical orientation and shrouded design.

Q: Do both parts have the same shrouded design?

A: Yes. Both the 1879337 and 1830648 feature a 4-side shrouded design, providing equivalent EMI shielding and mechanical protection.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and carry UL94 V-0 material flammability ratings. REACH status is unaffected for both parts.
