78286-410H Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78286-410H is a rectangular connector header featuring 10 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. This through-hole solder-terminated connector is designed for board-to-board applications and is classified as Active product status. The BERGSTIK® II series connector uses unshrouded, push-pull fastening with square male pins and tin-plated mating contacts. Finding equivalent substitute parts is necessary to address supply chain flexibility, alternative sourcing options, and specific application requirements such as contact finish preferences, temperature range needs, or RoHS compliance status.

Substitute Part Grouping Explanation

Substitute parts for the 78286-410H are qualified based on strict electrical and mechanical compatibility criteria. All substitute connectors must maintain the following core parameters: 10-position, 2-row configuration with 0.100" (2.54mm) mating pitch and row spacing, through-hole solder termination, push-pull fastening, unshrouded design, and square male pin contacts. Substitutes are grouped into two categories based on contact finish and material specifications:

Category A - Gold-Plated Mating Contacts: Parts with gold-plated mating surfaces (PBC05DAAN, PBC05DABN, PBC05DACN, PBC05DADN, PBC05DAEN, PBC05DAGN, 2310-6121-TG, A1-10PA-2.54DSA(71)) provide enhanced corrosion resistance and are suitable for applications requiring superior contact reliability.

Category B - Tin-Plated Mating Contacts: Parts with tin-plated mating surfaces (826632-5, 826942-5) match the original tin finish specification and are suitable for standard applications where gold plating is not required.

All substitute parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level, ensuring compatibility with standard PCB assembly and storage conditions.

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS3 Compliant):

The Sullins Connector Solutions PBC05 series (PBC05DAAN, PBC05DABN, PBC05DACN, PBC05DADN, PBC05DAEN) represents the most direct substitution path. These parts maintain phosphor bronze contact material matching the original 78286-410H, feature gold-plated mating contacts for enhanced reliability, and carry ROHS3 compliance. The extended operating temperature range (-65°C ~ 125°C) exceeds the original specification. Selection within the PBC05 series depends on post length requirements: PBC05DAAN (0.120" post), PBC05DABN (0.230" post), PBC05DACN (0.320" post), PBC05DADN (0.420" post), PBC05DAEN (0.520" post), and PBC05DAGN (0.720" post, discontinued).

Secondary Substitutes (Active Status, RoHS Compliant):

TE Connectivity AMPMODU Mod II series (826632-5, 826942-5) provides RoHS compliance with higher current rating (5A). The 826942-5 maintains tin-plated mating contacts matching the original finish, while 826632-5 features gold plating. Both support extended temperature range (-65°C ~ 105°C) and breakaway connector functionality.

Alternative Substitutes (Active Status):

3M 2310-6121-TG and Hirose A1-10PA-2.54DSA(71) offer gold-plated alternatives with ROHS3 compliance. The 3M part supports -55°C ~ 105°C operation with 3A current rating. The Hirose part operates at -55°C ~ 85°C with 3A current rating and includes 200V voltage rating specification.

Non-Recommended:

PBC05DAGN is discontinued at DiGi Electronics and should not be selected for new designs despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 78286-410H with any of the listed parts without PCB redesign?

A: Yes, all listed substitute parts maintain the core mechanical and electrical specifications: 10-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole solder termination, and push-pull fastening. However, verify post length compatibility with your PCB design, as post lengths vary across the PBC05 series (0.120" to 0.720").

Q: What is the difference between tin-plated and gold-plated mating contacts?

A: Tin-plated contacts (78286-410H, 826942-5) provide standard corrosion resistance suitable for general applications. Gold-plated contacts (PBC05 series, 826632-5, 2310-6121-TG, A1-10PA-2.54DSA(71)) offer superior corrosion resistance and lower contact resistance, beneficial for high-reliability or harsh environment applications.

Q: Are all substitute parts RoHS compliant?

A: No. The original 78286-410H is RoHS non-compliant. Most substitutes (PBC05 series, 826632-5, 826942-5, A1-10PA-2.54DSA(71)) are ROHS3 compliant. The 3M 2310-6121-TG is RoHS non-compliant, matching the original status.

Q: Which substitute offers the widest operating temperature range?

A: The Sullins PBC05 series (all variants) supports -65°C ~ 125°C, the widest range among all listed parts. This exceeds the original 78286-410H specification, which does not define an operating temperature range.

Q: What is the significance of post length variations in the PBC05 series?

A: Post length determines how far the solder tail extends from the insulation body. Selection depends on PCB thickness and solder joint requirements. Standard applications typically use PBC05DAAN (0.120" post). Thicker PCBs or applications requiring longer solder joints may require PBC05DABN through PBC05DAEN variants.

Q: Can I use 826632-5 or 826942-5 as direct replacements?

A: Yes, both TE Connectivity parts are mechanically and electrically compatible. The 826942-5 matches the original tin-plated finish, while 826632-5 provides gold plating. Both support higher current (5A) and extended temperature range (-65°C ~ 105°C) compared to the original specification.

Q: Is the Hirose A1-10PA-2.54DSA(71) suitable for my application?

A: The Hirose part is mechanically compatible and ROHS3 compliant with gold-plated contacts. However, its operating temperature range (-55°C ~ 85°C) is narrower than most alternatives. Select this part only if your application operates within this temperature window and requires the specified 200V voltage rating.
