Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTV-827M are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Number of Channels: 2
• Output Type: Transistor
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Current - Output / Channel: 50mA
• Voltage - Output (Max): 35V
• Vce Saturation (Max): 200mV
• Current Transfer Ratio (Min): 50% @ 5mA or higher
• Current Transfer Ratio (Max): 600% @ 5mA
• Rise / Fall Time (Typ): 4µs, 3µs
• Input Type: DC
• RoHS Status: ROHS3 Compliant

Substitutes are grouped into two categories: parametric equivalents (identical specifications) and manufacturer-recommended alternatives (compatible electrical performance with noted parameter variations).

Parameter Comparison

Engineering Selection Recommendations

LTV-827 (Lite-On Inc.): This part is a parametric equivalent to the LTV-827M with identical electrical specifications. The only difference is packaging format (Tube vs. standard packaging). Both parts are ROHS3 compliant, active in production, and suitable for direct substitution. Inventory availability is significantly higher at 188,067 pieces.

ISP827XG (Isocom Components 2004 LTD): This part is manufacturer-recommended as a substitute. It maintains identical channel count, output type, package, and most electrical parameters. The isolation voltage specification differs (7.5Vpk vs. 5000Vrms), and the operating temperature range is reduced to -30°C ~ 100°C. Current Transfer Ratio minimum remains at 50% @ 5mA. ROHS3 compliance and MSL rating are equivalent. This part is suitable for applications where the lower isolation voltage specification is acceptable.

ISP827XGB (Isocom Components 2004 LTD): This part is manufacturer-recommended as a substitute with the same package and channel configuration as ISP827XG. The key distinction is a higher Current Transfer Ratio minimum of 100% @ 5mA compared to 50% @ 5mA in the LTV-827M. Isolation voltage and operating temperature range match ISP827XG specifications. ROHS3 compliance and MSL rating are equivalent. This part is suitable for applications requiring higher current transfer efficiency.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and active product status, supporting long-term design reliability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can LTV-827 be used as a direct replacement for LTV-827M?

A: Yes. LTV-827 is a parametric equivalent with identical electrical specifications. The parts differ only in packaging format. Both are ROHS3 compliant and active in production.

Q: What is the key difference between ISP827XG and ISP827XGB?

A: The primary difference is the Current Transfer Ratio minimum specification. ISP827XG has a minimum of 50% @ 5mA, while ISP827XGB has a minimum of 100% @ 5mA. Both maintain identical channel count, output type, package configuration, and other electrical parameters.

Q: Are the Isocom ISP827 series parts compatible with the Lite-On LTV-827M in terms of package and pinout?

A: Yes. Both ISP827XG and ISP827XGB use the same 8-DIP (0.300", 7.62mm) through-hole package as the LTV-827M, supporting direct board-level substitution.

Q: What is the isolation voltage difference between LTV-827M and ISP827XG/ISP827XGB?

A: LTV-827M is rated for 5000Vrms isolation, while ISP827XG and ISP827XGB are rated for 7.5Vpk isolation. The LTV-827M provides higher isolation voltage capability. Substitution with Isocom parts is appropriate only when the lower isolation specification meets application requirements.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. LTV-827, ISP827XG, and ISP827XGB are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the LTV-827M compliance profile.

Q: What is the operating temperature range difference?

A: LTV-827M and LTV-827 operate from -30°C to 110°C. ISP827XG and ISP827XGB operate from -30°C to 100°C. Applications requiring operation above 100°C must use Lite-On parts.
