Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PC817X3CSP9F are qualified based on the following criteria:

Direct Electrical Equivalence: All substitute parts maintain identical isolation voltage (5000Vrms), single channel configuration, transistor output topology, current transfer ratio range (50% to 600% @ 5mA), maximum output voltage (80V), maximum output current (50mA), rise/fall time specifications (4µs/3µs), and Vce saturation maximum (200mV).

Allowed Parameter Variations:

• Operating temperature range may extend beyond the original specification
• Mounting type may differ (surface mount vs. through hole)
• Package configuration may differ (4-SMD vs. 4-DIP)
• Packaging format may differ (tube, tape & reel, or bulk)
• RoHS compliance status may vary (RoHS3 vs. original compliance level)
• Manufacturer may differ

Substitution Categories:

1. Direct Manufacturer Equivalent (LTV-816): Through-hole 4-DIP package variant of the same electrical specification, suitable for applications where through-hole mounting is required or preferred.

2. Similar Manufacturer Equivalent (LTV-816S-TA1): Surface mount 4-SMD package variant with extended operating temperature range, maintaining the same mounting technology as the original part.

Parameter Comparison

Engineering Selection Recommendations

PC817X3CSP9F (Original): Select this part when the original SHARP/Socle Technology manufacturer specification and surface mount 4-SMD gull wing package are required. This part maintains active product status.

LTV-816 (Direct Manufacturer Equivalent): Select this part when through-hole mounting is required or when a 4-DIP package is preferred for the application. This part is manufactured by Lite-On Inc., maintains active product status, and provides ROHS3 compliance. Operating temperature range extends to 110°C, providing additional thermal margin compared to the original specification.

LTV-816S-TA1 (Similar Manufacturer Equivalent): Select this part when surface mount technology must be maintained and extended operating temperature range (-50°C to 110°C) is required. This part is manufactured by Lite-On Inc., maintains active product status, and provides ROHS3 compliance. The extended temperature range accommodates applications with more demanding thermal environments.

Frequently Asked Questions (FAQ)

Q: Can LTV-816 be used as a direct replacement for PC817X3CSP9F in surface mount applications?

A: No. LTV-816 uses a through-hole 4-DIP package, while PC817X3CSP9F uses surface mount 4-SMD gull wing package. PCB layout and assembly process compatibility differ between these package types. For surface mount applications, use LTV-816S-TA1.

Q: What are the key electrical differences between the three parts?

A: All three parts are electrically identical in their core specifications: 5000Vrms isolation, single channel transistor output, 50% to 600% current transfer ratio, 80V maximum output voltage, and 50mA maximum output current. Operating temperature ranges differ: PC817X3CSP9F operates -30°C to 100°C, LTV-816 operates -30°C to 110°C, and LTV-816S-TA1 operates -50°C to 110°C.

Q: Are all three parts RoHS compliant?

A: Yes. PC817X3CSP9F is RoHS Compliant. LTV-816 and LTV-816S-TA1 are both ROHS3 Compliant, which represents a more recent compliance standard.

Q: Which substitute part should be selected for a new design?

A: For new surface mount designs, LTV-816S-TA1 is recommended based on active product status, ROHS3 compliance, and extended operating temperature range. For existing through-hole designs, LTV-816 provides compatibility with through-hole assembly processes.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: No. PC817X3CSP9F and LTV-816S-TA1 both use surface mount 4-SMD packages and can be used interchangeably on the same PCB. LTV-816 uses a through-hole 4-DIP package and requires different PCB footprint and assembly process.
