Phoenix Contact 1879421 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1879421 is a 16-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 1879421 is determined by the following critical parameters:

• Position Count & Pitch: 16 positions at 0.150" (3.81mm) spacing (non-negotiable for mechanical fit)
• Header Configuration: Male pins with 4-side shrouding and vertical orientation
• Electrical Ratings: Minimum 8A (IEC) and 250V (IEC) / 300V (UL)
• Mounting Method: Through-hole PCB mounting
• Housing Material & Flammability: PBT with UL94 V-0 rating
• Contact Finish: Tin plating

The Phoenix Contact 1830732 qualifies as a direct substitute based on matching all critical parameters. The primary difference is termination style: the 1879421 uses press-fit termination, while the 1830732 uses solder termination. Both achieve equivalent electrical and mechanical performance within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1830732 is the qualified substitute for the obsolete 1879421 based on the following factors:

Electrical Equivalence: Both parts meet identical current and voltage ratings (8A IEC, 250V IEC, 8A UL, 300V UL), ensuring no derating or circuit redesign is required.

Mechanical Compatibility: Identical position count (16), pitch (0.150" / 3.81mm), shrouding configuration (4-side), and insulation height (0.362") ensure direct PCB footprint compatibility.

Material & Compliance: Both utilize PBT housing with UL94 V-0 flammability rating and tin contact finish. The 1830732 carries ROHS3 compliance, exceeding the RoHS compliance of the 1879421.

Active Product Status: The 1830732 is classified as active, ensuring continued availability and supply chain stability compared to the obsolete 1879421.

Termination Consideration: The 1830732 employs solder termination versus the 1879421's press-fit termination. This difference requires assembly process adjustment but does not affect electrical or mechanical performance within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the 1830732 be used as a direct replacement for the 1879421 on existing PCBs?

A: Yes, the 1830732 provides direct mechanical and electrical substitution. The primary consideration is termination method: the 1830732 requires solder attachment rather than press-fit insertion. PCB footprints designed for the 1879421 are compatible with the 1830732.

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

A: Press-fit termination (1879421) uses mechanical insertion into plated through-holes without solder. Solder termination (1830732) requires thermal attachment via solder reflow or wave soldering. Both methods achieve equivalent electrical connection and current-carrying capacity within the specified 8A rating.

Q: Are there any dimensional differences that affect PCB layout?

A: The contact tail length differs slightly: 1879421 is 0.150" (3.81mm) versus 1830732 at 0.138" (4.60mm). Insulation height remains identical at 0.362" (9.20mm). These differences do not affect PCB footprint compatibility for standard through-hole mounting.

Q: Does the 1830732 meet the same compliance standards as the 1879421?

A: The 1830732 meets or exceeds all compliance requirements of the 1879421. Both carry UL94 V-0 flammability rating and tin contact finish. The 1830732 carries ROHS3 compliance, which supersedes the RoHS compliance of the 1879421.

Q: Why is the 1879421 classified as obsolete?

A: The 1879421 (COMBICON EMCV series) has been superseded by the 1830732 (COMBICON MCV series) within Phoenix Contact's product portfolio. The 1830732 provides equivalent functionality with active product status and improved compliance certifications.

Q: Can the 1830732 handle the same electrical loads as the 1879421?

A: Yes. Both parts are rated for 8A (IEC/UL) and 250V (IEC) / 300V (UL). Electrical performance and current-carrying capacity are identical across the specified operating range.
