Parameter Comparison

Engineering Selection Recommendations

853-43-100-10-001000 (Mill-Max Manufacturing Corp.)

This substitute maintains full compatibility with the 853-83-100-10-001101 across all critical electrical and mechanical parameters. The connector type differs (Receptacle vs. Socket), but both are part of the 853 series family and function as complementary mating components. The 853-43 offers enhanced current rating capability (3A vs. 1A), providing additional design margin for applications requiring higher current capacity. Contact length variation (0.102" vs. 0.094") remains within acceptable solder joint parameters. RoHS3 compliance and UL94 V-0 flammability rating are maintained. Packaging format is Tube. This part is suitable for direct substitution in applications where receptacle configuration is acceptable.

853-93-100-10-001000 (Mill-Max Manufacturing Corp.)

This substitute is electrically and mechanically equivalent to the 853-43-100-10-001000, with identical dimensional and performance specifications. The primary distinction is the contact finish on the post: Tin-Lead versus Tin. Both finishes are compatible with standard solder assembly processes. The 853-93 maintains 3A current rating, -55°C to 125°C operating temperature range, and full RoHS3 compliance. Packaging format is Tube. This part is suitable for direct substitution where Tin-Lead post finish is specified or preferred.

M50-3005045 (Harwin Inc.)

This substitute is from the Archer M50 series and maintains the critical 100-position, 0.050" pitch, 2-row configuration with through-hole solder termination and push-pull fastening. Contact finish on mating surface is gold (Flash specification). Current rating matches the main part at 1A. Operating temperature range is -40°C to 105°C, which is narrower than the main part (-55°C to 125°C) and may not be suitable for applications requiring full -55°C operation. Contact material is Phosphor Bronze rather than Beryllium Copper, and contact shape is Square rather than Circular. Insulation material is Polyamide (PA6T) Nylon 6T. RoHS3 compliance and UL94 V-0 flammability rating are maintained. Packaging format is Tube. This part is suitable for substitution in applications operating within the -40°C to 105°C temperature range where contact material and shape variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 853-43-100-10-001000 directly replace the 853-83-100-10-001101 in my application?

A: The 853-43-100-10-001000 is mechanically and electrically compatible for board-to-board applications requiring 100-position, 0.050" pitch connectors. Both parts share identical pitch, row spacing, mounting type, termination method, and fastening mechanism. The primary difference is connector type (Receptacle vs. Socket). If your application uses the 853-83 as a socket connector, the 853-43 receptacle will function as the complementary mating component. The enhanced 3A current rating of the 853-43 provides additional capacity beyond the 1A specification of the main part.

Q: What is the difference between the 853-43-100-10-001000 and 853-93-100-10-001000?

A: Both parts are identical in electrical performance, dimensional specifications, and current rating (3A). The distinction is the contact finish on the post: the 853-43 uses Tin finish, while the 853-93 uses Tin-Lead finish. Both finishes are compatible with standard solder assembly processes. Selection between these two parts depends on your assembly process specifications and post-finish requirements.

Q: Is the M50-3005045 suitable for applications requiring -55°C operation?

A: No. The M50-3005045 has an operating temperature range of -40°C to 105°C, which does not extend to -55°C. The main part 853-83-100-10-001101 and the Mill-Max alternatives (853-43 and 853-93) all support -55°C to 125°C operation. If your application requires -55°C minimum temperature operation, the M50-3005045 is not suitable.

Q: Why does the M50-3005045 have a Square contact shape while the main part has Circular contacts?

A: Contact shape is determined by the connector series design. The M50-3005045 is from the Harwin Archer M50 series, which uses square contacts, while the 853 series uses circular contacts. Both contact geometries are designed to provide reliable electrical connection at 0.050" pitch spacing. Contact shape variation is an allowable parameter difference for substitution purposes, provided all other critical parameters (pitch, number of positions, current rating, temperature range) are compatible with your application requirements.

Q: What packaging formats are available for these substitute parts?

A: The main part 853-83-100-10-001101 is supplied in Bulk packaging. The substitute parts are available as follows: 853-43-100-10-001000 in Tube packaging, 853-93-100-10-001000 in Tube packaging, and M50-3005045 in Tube packaging. Packaging format does not affect electrical or mechanical compatibility; it relates only to order quantity and handling requirements.

Q: Are all these parts RoHS3 compliant?

A: Yes. The main part 853-83-100-10-001101 and all three substitute parts (853-43-100-10-001000, 853-93-100-10-001000, and M50-3005045) are ROHS3 Compliant. All parts also maintain UL94 V-0 material flammability rating and Moisture Sensitivity Level 1 (Unlimited).

Q: Can I use the M50-3005045 in a high-current application?

A: No. The M50-3005045 is rated for 1A continuous current, the same as the main part 853-83-100-10-001101. If your application requires higher current capacity, the 853-43-100-10-001000 or 853-93-100-10-001000 (both rated 3A) are suitable alternatives.

Q: What is the difference in insulation height between these connectors?

A: Insulation height varies slightly across the parts: 853-83-100-10-001101 at 0.157" (4.00mm), 853-43-100-10-001000 and 853-93-100-10-001000 at 0.158" (4.01mm), and M50-3005045 at 0.173" (4.40mm). These variations are within acceptable mechanical design tolerances for board-to-board applications and do not affect electrical compatibility. Verify that your PCB layout accommodates the specific insulation height of the selected connector.
