Phoenix Contact 1879340 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1879340 is an 8-position terminal block header with male pins, shrouded on four sides, featuring a 0.150" (3.81mm) pitch for 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 8A (IEC/UL) and 250V (IEC) / 300V (UL), with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1879340 is determined by the following critical parameters:

• Position Count & Pitch: 8 positions at 0.150" (3.81mm) spacing
• Header Configuration: Male pins with 4-side shrouding
• Mounting Method: Through-hole vertical orientation
• Electrical Ratings: 8A current and 250V (IEC) / 300V (UL) voltage minimum
• Housing Material & Flammability: PBT with UL94 V-0 rating
• Compliance: RoHS compliance status

The substitute part Phoenix Contact 1830651 meets all critical substitution criteria. Both parts share identical position count, pitch, header type, mounting orientation, electrical ratings, housing material, and flammability classification. The primary difference lies in termination style (press-fit versus solder) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1830651 serves as a direct functional substitute for the obsolete 1879340 model. Both components maintain identical electrical performance specifications (8A, 250V IEC, 300V UL), mechanical configuration (8 positions, 3.81mm pitch, vertical through-hole), and safety certifications (UL94 V-0, PBT housing).

The 1830651 offers the advantage of active product status with current manufacturing support and ROHS3 compliance, compared to the obsolete status of the 1879340. The termination method differs (solder versus press-fit), which requires board design accommodation but does not affect electrical or mechanical compatibility.

The minor difference in contact tail length (0.138" versus 0.150") reflects the solder termination design and remains within acceptable mechanical tolerances for standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the 1830651 directly replace the 1879340 in existing designs?

A: Electrical and mechanical compatibility is confirmed. The primary consideration is termination method: the 1879340 uses press-fit termination while the 1830651 requires solder attachment. PCB pad design must accommodate solder termination specifications.

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

A: The 1879340 has a 0.150" (3.81mm) contact tail length while the 1830651 has 0.138" (4.60mm). This difference is inherent to the solder termination design and does not affect electrical performance or standard through-hole mounting compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The 1879340 is RoHS Compliant, and the 1830651 is ROHS3 Compliant. Both meet current RoHS requirements.

Q: What is the difference between the COMBICON EMCV and COMBICON MCV series?

A: Both are Phoenix Contact COMBICON series terminal block headers with identical electrical and mechanical specifications for this 8-position, 3.81mm pitch configuration. The series designation reflects different product lines within Phoenix Contact's portfolio.

Q: Is the 1830651 suitable for new designs?

A: Yes. The 1830651 holds active product status with current manufacturing availability, making it the appropriate choice for new applications requiring an 8-position, 3.81mm pitch terminal block header with solder termination.
