Phoenix Contact 1924321 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1924321 is a 4-position terminal block header with male pins, shrouded on all four sides, featuring a 0.200" (5.08mm) pitch for vertical through-hole mounting. This component is part of the COMBICON MSTBVA series and is rated for 16A at 400V (IEC) or 300V (UL). The part is active and in production with 1006 units currently in stock.

Equivalent and substitute parts are necessary when the primary part is unavailable, when supply chain optimization is required, or when design flexibility allows for alternative manufacturers meeting identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• 4-position configuration with 0.200" (5.08mm) pitch
• Vertical through-hole mounting with solder termination
• Male pin header with shrouded design
• UL94 V-0 flammability rating
• Insulation height of 0.472" (12.00mm)
• Tin contact mating finish
• 300V UL voltage rating minimum
• Active product status
• ROHS3 compliance

The following substitute parts meet these core criteria:

• 0395311004 (Molex Eurostyle ESE 39531) - 4-side shrouded, 15A UL rating
• 0395316004 (Molex Eurostyle ESE 39531) - 4-side shrouded, 15A UL rating
• 691311500104 (Würth Elektronik WR-TBL Series 311) - 4-side shrouded, 20A UL rating
• OQ0454500000G (Amphenol Anytek 06-508) - 4-side shrouded, 12A UL rating

The part 0395315004 (Molex) is listed but features 2-side shrouding instead of 4-side shrouding, making it a partial substitute only for applications where reduced shrouding is acceptable.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the Phoenix Contact 1924321.

Primary substitutes (0395311004, 0395316004, 691311500104, OQ0454500000G) are fully qualified alternatives. Current rating variations exist: the Würth 691311500104 offers 20A capacity, exceeding the original 16A specification; the Molex options provide 15A; the Amphenol option provides 12A. Voltage ratings remain constant at 300V UL across all options.

Contact tail length variations range from 0.130" (3.30mm) to 0.157" (4.00mm), compared to the original 0.154" (3.90mm). These minor dimensional differences may require PCB layout verification for through-hole clearance and solder joint formation.

Housing material composition differs: Phoenix Contact uses Polyamide (PA), Molex uses Polyamide (PA66), Würth uses Polybutylene Terephthalate (PBT), and Amphenol uses Thermoplastic Resin. All maintain UL94 V-0 flammability certification.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0395311004 as a direct replacement for Phoenix Contact 1924321?

A: Yes. Both parts share identical pitch (5.08mm), position count (4), shrouding (4-side), mounting type (through-hole), and voltage rating (300V UL). The Molex part carries a 15A UL rating versus the original 16A, which is acceptable for applications operating at or below 15A. All compliance certifications (ROHS3, UL94 V-0) align.

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

A: Contact tail length affects solder joint depth and PCB hole engagement. The Phoenix Contact 1924321 has a 0.154" (3.90mm) tail, while substitutes range from 0.130" to 0.157". These variations are within standard PCB design tolerances for through-hole components. Verify your PCB hole depth and solder pad design accommodate the substitute part's tail length.

Q: Why is Molex 0395315004 listed separately?

A: The 0395315004 features 2-side shrouding instead of 4-side shrouding. While it maintains the same pitch, position count, and electrical ratings, the reduced shrouding changes the mechanical profile and EMI shielding characteristics. Use this part only if your application permits reduced shrouding.

Q: Are there current rating limitations when substituting?

A: Yes. The Amphenol OQ0454500000G is rated for 12A UL, below the original 16A specification. Use this part only in applications operating at 12A or below. The Würth 691311500104 (20A) and Molex options (15A) are suitable for the original 16A design margin.

Q: Do all substitutes meet the same compliance standards?

A: All listed substitutes are ROHS3 compliant and carry UL94 V-0 flammability ratings. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all except Würth 691311500104, which is Not Applicable. This does not affect substitution eligibility for standard applications.

Q: What is the inventory status of substitute parts?

A: Molex 0395311004 has 13,919 units in stock; Molex 0395316004 has 2,923 units; Würth 691311500104 has 3,445 units; Amphenol OQ0454500000G has 6,470 units. All substitutes maintain higher inventory levels than the original Phoenix Contact part (1,006 units).
