Molex 0395364521 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The Molex 0395364521 is a 21-position terminal block header featuring male pins with four-side shrouding, 0.200" (5.08mm) pitch, and right-angle through-hole mounting. This component is part of the Eurostyle ESE 39536 series and is designed for solder termination applications requiring 300V rated insulation and UL94 V-0 flammability compliance.

The 0395364521 carries an obsolete part status. Equivalent and substitute parts from the same manufacturer series provide active alternatives with maintained electrical and mechanical compatibility while offering current availability and updated material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0395364521 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 21
• Pitch: 0.200" (5.08mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination Style: Solder
• Mounting Type: Through Hole
• Voltage - UL: 300 V
• Operating Temperature Range: -40°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Contact Material: Brass
• Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts 0395360021 and 0395360521 maintain all mandatory parameters while differing in contact mating finish (tin or gold), housing material composition (PA66 versus PA46), and current rating specifications. These variations remain within acceptable substitution criteria for the Eurostyle ESE 39536 series.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Molex 0395360521

The 0395360521 is the manufacturer-recommended substitute for the obsolete 0395364521. Both components feature gold contact mating finish, identical electrical ratings (300V UL), matching operating temperature range (-40°C ~ 105°C), and UL94 V-0 flammability compliance. The 0395360521 carries active product status with current manufacturing support and maintains ROHS3 compliance. The housing material upgrade to PA66 (Nylon 6/6) provides enhanced material specifications while preserving mechanical and electrical compatibility.

Secondary Alternative: Molex 0395360021

The 0395360021 serves as an alternative substitute with identical mechanical and electrical specifications. This part features tin contact mating finish instead of gold and is also active in production. The tin finish may be suitable for applications where gold plating is not required. The current rating of 18A exceeds the original 15A specification, providing additional capacity margin.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, EAR99 export classification, and HTSUS code 8536.69.4040. Moisture sensitivity level remains at MSL 1 (Unlimited) across all variants. The UL94 V-0 flammability rating is preserved in all substitutes, ensuring compliance with fire safety requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0395360021 and 0395360521 be used interchangeably with the 0395364521?

A: Both substitute parts maintain identical mechanical fit, electrical ratings (300V), operating temperature range (-40°C ~ 105°C), and mounting configuration (21-position, 5.08mm pitch, right-angle through-hole). The primary differences are contact mating finish (tin versus gold) and housing material composition (PA66 versus PA46). Selection depends on application requirements for contact finish and material properties.

Q: What is the difference between the tin finish (0395360021) and gold finish (0395360521) contacts?

A: Contact mating finish affects corrosion resistance and electrical contact characteristics. Gold finish provides superior corrosion resistance and is specified in the original 0395364521. Tin finish offers cost efficiency and is suitable for applications without corrosive environmental exposure. The 0395360521 maintains the gold finish specification of the original part.

Q: Why does the 0395360021 have a higher current rating (18A) than the original part (15A)?

A: The current rating difference reflects updated material specifications and manufacturing standards. The 18A rating of the substitute parts indicates improved current-carrying capacity while maintaining the same 300V voltage rating and operating temperature range. Applications requiring the original 15A specification remain compatible with the higher-rated substitutes.

Q: Are there any compatibility concerns with the housing material change from PA46 to PA66?

A: Both polyamide materials maintain UL94 V-0 flammability compliance and identical operating temperature range (-40°C ~ 105°C). PA66 (Nylon 6/6) offers enhanced mechanical properties compared to PA46 (Nylon 4/6). The material upgrade in substitute parts does not introduce compatibility issues for through-hole solder termination applications.

Q: What is the inventory status of these substitute parts?

A: The 0395364521 (original, obsolete) has 726 pieces in stock. The 0395360021 (substitute) has 825 pieces available. The 0395360521 (manufacturer-recommended substitute) has 820 pieces in stock. All substitute parts are active products with current manufacturing availability.

Q: Do all parts carry the same RoHS and export compliance certifications?

A: Yes. All parts including the original and substitutes are ROHS3 compliant, carry EAR99 export classification, and share HTSUS code 8536.69.4040. Moisture sensitivity level is MSL 1 (Unlimited) for all variants, indicating no special storage or handling requirements.
