Phoenix Contact 1849040 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1849040 is a 5-position terminal block header with male pins, shrouded on 4 sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON MSTBVA series and is actively manufactured. Terminal block headers are essential interconnection components in industrial control systems, power distribution, and signal routing applications where reliable solder-terminated connections are required. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative inventory sources.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1849040 is determined by strict alignment of the following critical parameters:

Position Count & Pitch: Both main and substitute parts must have exactly 5 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
Header Type & Orientation: Vertical orientation with male pins and 4-side shrouding is mandatory for form-factor compatibility.
Termination & Mounting: Solder termination and through-hole mounting must be identical.
Voltage Rating: Minimum UL voltage rating of 300 V is required.
Flammability Compliance: UL94 V-0 rating ensures material safety standards are met.
RoHS & MSL Compliance: ROHS3 compliance and MSL 1 rating confirm environmental and handling requirements.

The TE Connectivity AMP Connectors part 796636-5 meets all these criteria and qualifies as a direct substitute.

Engineering Selection Recommendations

Both the Phoenix Contact 1849040 and TE Connectivity 796636-5 are actively manufactured components with identical compliance certifications (ROHS3, UL94 V-0, MSL 1). The TE Connectivity substitute provides equivalent electrical performance with a higher current rating (15 A vs. 12 A), making it suitable for applications requiring additional current capacity. Both parts meet the same voltage (300 V UL) and flammability standards. The primary differences are cosmetic (color) and material specification (PA vs. PA66 nylon), which do not affect functional interchangeability in standard terminal block applications. Contact tail length variation (0.154" vs. 0.138") is within acceptable tolerance for through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796636-5 be used as a direct replacement for the Phoenix Contact 1849040?

A: Yes. Both parts share identical position count (5), pitch (5.08mm), orientation (vertical), type (male pins, 4-side shrouded), termination (solder), mounting (through-hole), voltage rating (300 V UL), and flammability compliance (UL94 V-0). Functional interchangeability is confirmed.

Q: What are the differences between these two parts?

A: The TE Connectivity part has a higher current rating (15 A vs. 12 A), different housing material specification (PA66 vs. PA), different color (green vs. gray), and a slightly shorter contact tail length (0.138" vs. 0.154"). These differences do not affect electrical or mechanical compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry UL94 V-0 flammability ratings, and have MSL 1 moisture sensitivity levels. Both are actively manufactured and meet identical environmental and safety standards.

Q: Does the contact mating finish difference (gold vs. tin) affect substitution?

A: The contact finish difference does not prevent substitution. Both finishes provide adequate electrical contact and corrosion resistance for standard terminal block applications. The choice between gold and tin is typically driven by application-specific requirements and cost considerations.

Q: Will the shorter contact tail length of the TE part affect PCB mounting?

A: The contact tail length difference (0.138" vs. 0.154") is within standard manufacturing tolerances for through-hole terminal block headers and will not affect PCB mounting or solder joint quality in typical applications.
