Key Parameters

Substitute Part Grouping Explanation

Substitution for the MA35-52P-2DS(71) is based on strict electrical and mechanical parameter matching within the MA35 series. The substitute part MA35-52P-2DS(51) qualifies as a direct equivalent because it maintains identical specifications across all critical parameters: 52-position configuration, 2.00mm pitch, 2-row layout, through-hole right-angle mounting, 2A current rating, 200VAC voltage rating, and -55°C to 85°C operating temperature range. Both parts share the same contact geometry, material composition (brass contacts with tin finish), insulation material (polyamide/nylon), and flammability rating (UL94 V-0).

The primary distinction between these parts is product status: MA35-52P-2DS(71) is obsolete, while MA35-52P-2DS(51) is active. The substitute part also includes RoHS compliance certification and improved moisture sensitivity level (MSL 1 - Unlimited versus Not Applicable), making it suitable for replacement in new designs and ongoing production.

Parameter Comparison

Engineering Selection Recommendations

The MA35-52P-2DS(51) is the direct substitute for MA35-52P-2DS(71). Selection of the substitute part is justified by the following factors:

Electrical and mechanical compatibility is complete across all specified parameters. Both parts maintain identical pitch, position count, current and voltage ratings, and operating temperature range. Physical dimensions and contact geometry are identical, ensuring PCB layout compatibility without modification.

Product status transition from obsolete to active ensures long-term availability and supply chain continuity. The substitute part carries RoHS compliance certification, meeting current regulatory requirements for electronic components in many jurisdictions. The improved moisture sensitivity level (MSL 1 - Unlimited) provides enhanced reliability for storage and handling in standard industrial environments.

No design changes or PCB rework are required when transitioning from MA35-52P-2DS(71) to MA35-52P-2DS(51).

Frequently Asked Questions (FAQ)

Q: Are MA35-52P-2DS(71) and MA35-52P-2DS(51) mechanically interchangeable?

A: Yes. Both parts share identical mounting type (through-hole, right-angle), pitch (2.00mm), position count (52), row configuration (2 rows), and contact geometry. No PCB modifications are required for substitution.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certifications. MA35-52P-2DS(71) is obsolete, while MA35-52P-2DS(51) is active. MA35-52P-2DS(51) includes RoHS compliance and an improved moisture sensitivity level rating (MSL 1 - Unlimited).

Q: Can MA35-52P-2DS(51) be used in applications originally designed for MA35-52P-2DS(71)?

A: Yes. Electrical performance, current rating (2A), voltage rating (200VAC), operating temperature range (-55°C to 85°C), and all mechanical specifications are identical. The substitute part is fully compatible.

Q: What does the packaging difference mean?

A: MA35-52P-2DS(71) is supplied in standard packaging, while MA35-52P-2DS(51) is supplied in bulk packaging. This affects order quantities and handling but does not impact component performance or compatibility.

Q: Is RoHS compliance important for my application?

A: RoHS compliance is a regulatory requirement in many markets and industries. MA35-52P-2DS(51) meets RoHS standards, while MA35-52P-2DS(71) does not specify compliance. For new designs and products destined for regulated markets, the RoHS-compliant substitute is recommended.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance, current capacity, voltage handling, and temperature stability. All functional specifications are equivalent.
